Are you intending to qualify PQR in
Single Vee butt weld - No welding from Root side ?
Double Side Weld with back grinding DPT from root side ?
This will decide the PQR purging requirement
Thanks

Dear experts,--Could you please check and advise the below query.
- Whether the back purging is a quality requirement or the ASME code is insisting on back purging on SS material while doing the GTAW process.
- Whether we can qualify SS -GTAW PQR without back purging or the ASME code does not allow doing PQR for austenitic steels without a back purge?
- Kindly advise how to do it without purging in SS GTAW Welding . Planning for PQR as well
